Successful hydroforming isn’t just about the technology; often it’s about the strategy. A forward-thinking die development plan, global die standardization, and knowledge about forming materials other than mild steel are three components that can go a long way in making hydroforming a viable option.

ASTM A513 (Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing) is a conventional specification that governs tube for many uses, and hydroformers have been relying on tube made to this standard for many years. However, some hydroformers think that some aspects of this specification aren't appropriate for hydroforming: Some portions of it need to be tightened up and others loosened. Developing a modified specification specifically for hydroforming likely will result in less expensive tubing and fewer failures.
